PRECURSOR OF A CATHODE ACTIVE MATERIAL FOR A LITHIUM SECONDARY BATTERY, CATHODE ACTIVE MATERIAL, METHOD FOR MANUFACTURING THE CATHODE ACTIVE MATERIAL, AND LITHIUM SECONDARY BATTERY INCLUDING THE CATHODE ACTIVE MATERIAL

摘要

The present invention relates to a precursor for a lithium secondary battery, to a cathode active material including the precursor, to a method for manufacturing the cathode active material, and to a lithium secondary battery including the cathode active material. More particularly, the precursor is plate-shaped and has a thickness of about 1 nm to about 30 nm, and is represented by following chemical formula 1: [Chemical formula 1] NixCoyMn1-x-y-zMz(OH)2. In chemical formula 1, 0
